Ghost Booster GO Guaranteed

Guaranteed Minimum Win is a 'safety net' feature, often found in the free spins bonus of high-volatility slots. If the total winnings at the end of the bonus round are less than a predetermined minimum amount (e.g., 10x the bet), the bonus is retriggered or additional spins are awarded until the minimum amount is reached. The core of this feature is to mitigate the extreme frustration players feel from a 'dud bonus'—a bonus round that ends with little to no winnings after being entered with high expectations.

A Collection Meter is a system where a progress bar or gauge (meter) is present on the game screen, which fills up each time the player collects specific symbols or performs certain actions. The core of this feature is to provide the player with a long-term goal that goes beyond the success/failure of a single spin. When the meter is full, an instant prize or a special bonus is awarded as a reward. This provides players with a growth-type fun, similar to 'leveling up' or 'completing a quest'.
